To all/whom it may concern.' Y

Be it known that I, EoRG'Es BAUJARD, a citizen of the French Republic, residing at Paris, France, have invented certainl new and useful Improvements in Cloth-Pressing Machines, of which the following is a specication.

Machines for pressing cloth are generally used by tailors and mainly serve for attenliting of the iron is also effected very rag.

idly owing to the counterweights and t cessation of the hydraulic pressure.

A. machine according to this invention isz shown by way of example in the accompanying drawings:

Figure l 1s a longitudinal vertical section. Fig. 2 is a plan view on the line A-B, Fig. 1 of the machine the upper part of the' machine having been omitted. Fig. 3 is a front ele'- vvation of the machine. show the pressure lever and the transmission segment 1n various positions. Fig. 7-is an elevation of Fig. 5 seen from the right hand side. Fi 8 shows on a larger scale in cross section t e movable arm Supporting the smoothing iron.

In the form of construction shown all the parts of the machine are mounted upona .frame composed of two uprights 1 and 2 connected by transverse bars 3 and 4. At the upper part of the frame a working table 45 5 is mounted. A jaw 6 for maintaining the cloth upon the table is pivotally mounted upon the frame. yA supporting table 7 serves for carrying the parts of the cloth which are not to be worked upon, the vert-ical positionof said table being 'adjustable by means of a device consisting of a rack and a pinion to be operated by hand by means of a handle 8. The smoothing iron 9 is held by means of a ball joint 10 at the end of a movable cylindric arm l1. The smoothing iron can be vmoved in any direction by means of its Spceiieaton of Letters Patent.

handle 12. The movable arm 11 traversesy j'two supports mounted at the end of a beam 17. One of these supports consists of a bearing surface 13 forming a slide and of a rol-ler 1.4 which facilitates the displacement ofthe movable arm 11. The arm 11 is supported by' the bearin surfaces 13-,15 and the rollers 14%16. he rollers have an inl dentation at the middle so that their remaining surfaces are tangential with the surface of the tubular arm 11 at two points 38-39 only (Fig. 8). Owing to this arrangement the tubular arm 11 moves upon the rollers without slipping. The beam 17 is mounted at the end of a vertical standard 18 which is pivotally mounted in a suitable support 19 ixed` upon a bracket 20. The vertical arm 18 has at its lower end an eX- tension 19 formed by a rack' with which engages a loose pinion 37 rigidly connected with a pinion 36 having two teeth. This f rack is guided at its lower part in the transverse bar 4. t carries at its up er vpart ma stud 2l upon which the en'd of a ever22 is loosely mounted. At the other end of said lever 22 a oounterweight 23 is arranged. Be-

low the loose pinion`36 a segment 24 with two teeth is mounted which 1s rigidly con-- i nected with a pressure lever 25 and which is adapted to engage /with the pinion 36 when j the-two teeth of this pinion are in front of the teeth oi the segment. The' other end o't vthe pressure lever 25 is loosely secured to therod 26 of-a hydraulic press 27 mounted upon the frame. The lever 22 carrying the counterweight and which can pivot around the axle 28 isconnected by a connecting rod 29 with a pedal lever 30 adapted to turn around a pivot 31" and carrying the counterweight 32 and a pedal 33. Below this L lever a valvehandle 34 is arranged which serves for operating the hydraulic press 27, this valve handle is held normally in lifted position.r A nger 35 fixed upon the axle 28 serves for limiting the movement :of the pressure lever 25.

The connecting of the sector 24 with the pinion 36 is shown lin detail in Fig. 7, .this sector having two teeth and is rigidly connected with the pressure lever 25, and opposite the same there is mounted the pinion 36'haviug two teeth and further'a pinion 37 having a greater ynumber of teeth and which stands opposite to the rack 19.

The loperation of the apparatus is as folpedal` 33 has to be depressed. Throughy the intermediary of the connecting rod 29 and of the lever 22 With counterweight the rack 19 with its stud 21 and consequently the movable arm 11 and the smoothing iron are drawn along. 1 At the same time the rack makes revolve the pinion 37 and with it the pinion 36 yvith two teeth, Which thus is brought before the toothed sector with. which it engages as shownin Fig. 6 as soon as this sector is displaced. At the end ot' its stroke the pedal lever operates the valve of the hydraulic press 27, and the pressure lever 25 is lifted. The tWo teeth of the segment 24C mesh lwith the teeth of the pinion 36 and through they-intermediary of the pinion 37 they make tlierack descend and produceA the required pressure. To lift the smoothinar iron the pedal is released, the counter- Weight 23 through the intermediary of its lever bringing the parts-back to their normalposition and permitting the valve handle to rise and release the pressure in the hydraulic press. Owing to this arrangement there has been realized a machine for pressing cloth. in which the `lowering and lifting;r movements of the 'smoothing iron are e'ected lr'apidly'; the hydraulic press enters into action only at the end of the descending movement.

The apparatus which forms the object of this invention cannot only be used for pressing;r cloth but it further can be used, for example, as a 'press for stamping, punching, andl the like, not only clot-h but leather, Wood, sheet metal and the like. rllhis machine o'ers in all these cases the advantages accruing;r from its double movement, namely,

Low/dais lever, a pull rod connecting said pedal lever With said lever of the standard -to bring the iron ltoward the Working tablewvvhen said pedal lever -is being depressed, a pinion en'pgagzgingr with lsaid rack, a toothed segment connected with said pinion, a pressure lever "for communicatingrr inal pressure to the smoothing" iron, a toothed segment at the inner end of said pressure lever adapted to mesh With said segment of the pinion, a'hydraulic cylinder. a piston in said cylinder with which the end of the pressure lever is connected, and a valve for admitting fluid under said piston situated under said pedal lever so that it is opened only when the pedal er has been depressed for a certain extent, substantially as described and for the purpose set forth.
